“…The second step of weight loss occurring in between 182 C and 410 C could be attributed to the evaporation and degradation of DBSA and the oxidation process of the PANI structure [17,[34][35][36][37]. The weight loss corresponding to the third step (410 w 600 C) is mainly due to thermal decomposition of PANI into some chemical forms [34][35][36][37][38][39]. The relative weight loss (W 1 , W 2 ) of the first and second stages with respect to PANI, their maximum decomposition temperatures (T 1 -T 3 ) and residue at 600 C are given in Table 1.…”

“…Because of this, the properties of blends of PANI with commercial polymers were investigated in order to obtain materials that combine the electrical and optical properties of the first with the mechanical properties of the second [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] . The methods used to prepare blends and composites of PANI-conventional polymers include solution [1][2][3][4] , polymerization in situ [5][6][7]4 , fusion [8][9][10] , emulsion [11][12][13][14][15] , and inverse emulsion [16][17][18][19] . Poly(vinylidene fluoride) -PVDF is a conventional polymer used as matrix for PANI blends.…”

Poly(vinylidene fluoride)/polyaniline blends of different composition were synthesized by chemical polymerization of aniline in a mixture of Poly(vinylidene fluoride) and N,N-dimethylformamide and their thermal and mechanical behavior was investigated as a function of the polyaniline doping level and the composition using thermogravimetric analysis, differential scanning calorimetry, dynamic mechanical analysis and tensile tests techniques. The results showed the blend obtained presents a good thermal stability with low weight loss up to 300 °C, assigned to water and solvents evaporation. The glass transition and melting point is not affected by the PANI content in the blend, showing that polymers are no miscible. The films produced present a good sustainability; however the presence of the conducting polymer in the blend increases the tensile strength and the Young modulus, while diminishes the elongation at break, as compared to pure PVDF.

“…Stable emulsion systems were achieved by using appropriate surfactant systems, [2][3][4][5][6] or by using dodecylbenzene sulfonic acid (DBSA), which acts as both surfactant and doping agent. [7][8][9][10][11][12][13] The presence of Pani in a blend usually contributes to a decrease in the mechanical performance of the polymer matrix because of its intrinsically brittle nature. Therefore, it is important to choose a polymer matrix with an improved toughness and flexibility to accommodate the dispersed Pani and still maintain acceptable mechanical properties.…”

Conducting polymer blends based on styrene–butadiene–styrene (SBS) triblock copolymer and polyaniline doped with dodecylbenzene sulfonic acid (Pani.DBSA) were prepared by different procedures: mechanical mixing (MM) and ‘in situ’ polymerization (ISP) methods. The ISP blends exhibited higher levels of electrical conductivity, as compared to MM blends. The scanning electron micrographs of the ISP blend were characterized by the presence of microtubules, which favored the formation of the conducting pathways inside the SBS matrix. From dynamic mechanical and dielectric analysis, it was possible to suggest a higher interaction degree of the polyaniline with the polystyrene phase of the block copolymer. Blends prepared by ISP method displayed also higher dielectric constant and higher dielectric loss factor than blends prepared by MM method.magnified image
